'1 0 all whom it may concern:

Be it known that I, SERGiUs TnuoonowrrsoH, a subject of the Emperor of Russia, residing at Mjasnitzkaja, N o. 24, Moscow, in

the Empire of Russia, engineer, have invented a certain new and useful Ventilating System for Rooms and the Like, of which the following is a specification, reference being had to the drawings hereunto annexed and to the figures and reference-numerals marked thereon, that is to say According to the usual systems of ventilation by means of fresh or outer air which has not been previously heated, the air is introduced into the apartment through apertures which are located along the upper part of the walls or in the ceiling and sometimes provided with filtering or ventilating devices while the heated foul air passes away through outlets provided in the walls near to and slightly above the floor.

The object obtained by this arrangement is to thoroughly mix the fresh air coming from the outside with the vitiated air in the room. In practice such an arrangement of inlets and outlets is attended with an unde- -sirable draft which is most infurious in the case of invalids and, especial y in large rooms, results in an irregular distribution of the incoming air, and affects only the strata of vitiafed air nearest to the outlets along a the floor, while it has no appreciable effect upon the large volume of vitiated air in the central area of the room. It was for this reason that this system of ventilation was abandoned and ventilation by means of heated air was introduced. Although, how ever, some of the evils attending the above described cold air system of ventilation could thus be avoided yet they were replaced b other drawbacks, the chief of which is t at air, previouly heated contains microscopically small particles of dust and other impurities which pass through any of the usual filters available for the pur ose and that the air in the room ventilated by such heated air which is generally passed through dark heated tubes cannot be compared withand hygienically does not possess the same value as fresh air which has not been previously heated.

- Nowthe object of the present invention is to utilize the advantages of'the two aforesaid 'der.

systems of ventilation while avoiding the disadvantages thereof. This result is attained by introducing into the apartment at or near the ceiling thereof fresh outer air which has passed through filtering devices and in extracting the foul or vitiated air from the room through outlets arranged in or near the ceiling, and preferably provided with fans.

Experiments have shown that fresh cold air has little or no aifinity for foul or vitiated heated air and when the same is introduced into an apartment it has great difliculty in mixing with the foul heated air, so that a number of separate strata are formed which slide one along the other without an complete mixture resulting. By the pecu 'ar arrangementof inlets and outlets according to the present invention this principle is to some extent utilized and the result attained is that the incoming fresh air which owin to its lower temperature and greater specific gravity falls from the ceiling toward the floor,

comes into contact with the lighter ascending warmer foul or vitiated air along a comparatively extensive area or surface and conse quently causes the incoming fresh air to become more or less heated without mixing to any great extent with the foul or vitiated a1r, while furthermore by the peculiar arrangement of inlets and outlets a draft is altogether avoided.

This invention is capable of being carried of partitions or beams provided beneath the ceiling 5 of the room and each furnished for its entire length with a number of horizontal perforations or ways 2 arranged in close or- Underneath these beams 1 is fastened by suitable means a layer of filtering mater al 3 consisting of one or more sheets. of wire gauze or other suitable perforate or porous material, the points of attachmentthereof to the beams 1' being covered by decorative bands or moldings 4 of any desired pattern.

Fresh air is introduced into the space between the ceiling 5 and the layer of filtering material 3 by means of a number of passages 6 which if desired may be provided with fans 7 and b reason of the perforations 2 in the beams t e air is enabled to circulate throughout the entire area of said space. The outlet passages for the foul or vitiated air are according to this invention provided by means of pipes 8 passing through the ceiling itself or passages 9 passing through the wall of the room in immediate proximity to the ceiling. Air extractors or fans 10 of any suitable construction and actuated in any suitable way may be provided if necessary in the pipes 8 or passages 9 in order to assist the removal of the foul or vitiated air from the room.

The fresh air introduced by the various inlets 6 is distributed over the entire area of the s ace between the ceiling 5 and the layer of tering material 3 and passes into the room through said filtering layer 3, after the particles of dust and the ke have been arrested thereby, in finely divided inappreciable streams or currents. This fresh cool air entering by the ceiling descends toward the floor of the room and thus comes into fairly intimate contact with the ascending foul warm air, which also is or may be sucked up by the fans 1O, without becoming mixed with such foul air to any serious extent and the incoming cold air is thereby more or less heated before reaching the occupants of the room, so that'the general atmosphere of the room is maintained in the required fresh condition without being actually cool. Thus the danger to the occupants of the room 0% catching cold is avoided and, owing to the eculiar arrangement of'the inlets and outets, no current of air is apparent to the occupants, even if, both in the inlets and outlets, ventilators or fans are in operation so that with the introduction of a moderate volume of air into the room the atmosphere thereof can be maintained in a fresh and Wholesome gonpition vn'thout creating any appreciable ra t.

In the example given at Figs. 2 and 3 the ventilation system corresponds essentially with the construction illustrated in Fig. 1, except that in this case a space covering the entire area of the ceiling is not inclosed by the ventilating and filterin layer 3 but in lieu thereof a'distributing ox, channel, or conduit 11 of a flattened section is provided beneath the ceiling and covered on its under side with a layer of gauze or'other suitable filtering material 12, and this flat diStKl bllt? eea eie ing box or channel which extends all round or it might be across the ceiling as shown at Fig. 3 is connected at one or several points with the air inlets 6. Outlets 8 and 9 are provided in the same way as hereinbefore shown and described with respect to Fi 1 that is to say they are arranged in the cei 'ng of the room or in the wall in close proximity to the ceiling.

It will be understood that the constructive details hereinbefore shown and described are merely iven by way of example and are capable 0% considerable variation without departing from the spirit of the invention.

By the means hereinbefore described the foul or vitiated air is removed from a room or apartment or the like and fresh air is introduced thereinto without to any great extent mixing with the former while at the same time the incoming air is more or less heated by passing in close proximity to the outgoing warm but foul air and thus the atmosphere of the room is maintained in a wholesome condition from a hygienic standpoint and by reason of the peculiar relative positions of the inlets and outlets this is achieved without creating an appreciable draft.

Having now particularly described and ascertained the nature of the said invention and in what manner the same is to be per formed I declare that what I claim is I.
